water passing through water heatingappa ratus.

One object of my present invention is to provide simple and effective means for properly dividing and obtaining a measure of the amount of water passing through a common supply connection to a plurality of water heaters.

Another object of my invention is to provide simple and effective apparatus for measuring the amount of water passing through a common supply connection'to a plurality of water heaters, and for obtaining an individual measure of the total amount of Water discharged from each heater, regardless of whether some or all of this water may have come from some other source than said common supply connection.

The various features of novelty which characterize my invention, are pointed out with particularity in the claims annexed to and forming a part of this specification. For a better understanding of the invention, however, and of the advantages possessed by it, reference should be had to the accompanying drawings and descriptive matter in which I have illustrated and described a preferred form of apparatus embodying my invention.

Of the drawings: Figure l is an elevation, partly in section, of a combined water heating and measuring plant; and Fig. 2 is a section on the broken line 2-2 of Fig. 1.

In the drawings A represents a pipe supplying water to be heated to a plurality of water heaters D. The pipe A may and in such an arran 'ement as is shown in the drawings would ordinarily run from a condenser hot well. In theparticular arrangement shown there are two water heaters D,

which are similar to each other. The pipe A discharges into the inlet chamber B of a receptacle B. As shown, the outlet compartments B of the receptacle B, of which there are one for each heater D, are each separated from the inlet chamber by a weir plate C formed with one or more discharge notches or V-orifices C at its upper edge. Each outlet compartment B is connected by a pipe B" to the water inlet of a corresponding heater D. To avoid eddy currents onthe supply side of each weir G, baflles B and a peri orated diaphragm B are interposed between the weir plates and the discharge end A of thcpipe A which extends into the weir receptacle. \Vith this arrangement the inlet compartment 13 is divided into a central chamber into which the pipe A discharges and two still water chambers I), one adjacent each weir. i

The means for measuring the water passing through the weir orifices C, comprise a float chamber E closed at its lower end and extending into the upper end of the compartment B between the batlles B The float chamber E is connected by the pipes E to the still water chambers 6 below the lowermost level of flow over the "weirs C. A .float F working in the float chamber E is connected to and operates suitable indicating or recording mechanism located in the receptacle (l mounted on top of the receptacle B. Ports B are formed in the ballles 13 above the water line to equalize the vapor pressure in the still water chamhers I) and central chamber of the receptacle B" and vapor equalizing ports E are formed in the cylinder E above the water level.

Each heater D in the particular form shown is divided into an upper heating chamber 1) and a lower Wei-r chamber D by the horizontal partition D These chambers are connected at one end of the heater, and a bafile D and perforated diaphragm D are providedto insure a quiet flow of water from the chamber D into the stillwater compartment cl of the weir cha1nber D.

water chamber (5 into the outlet compartment of the weir chamber over a weir CA which may be generally similar to the weirs C hereinbefore described. p g

D represents a pipe connection for equal- The water overflows from the still izing the vapor pressure in the chambers D and D and D* represents ports formed in the baiiie D for the same purpose. The still water chambers Z) and the heaters D are connected to the atmosphere by the vent piping P and the usual non-return valve In the chamber D are located the'usual bafiies or trays H over wich the water to be heated flows in film-like and broken streams. The water is discharged onto the trays H through spouts D leading from the sides of a water trough D located at the top of the chamber D and into which the corresponding pipe B discharges. heating the water passing to the heaters D is supplied through a common steam supply pipe I and the branches 1' thereof which run one to each heater.

D represent the discharge pipes from the heaters which may be connected to boiler feed water pumps or other devices for handling or utilizing the water heated. As shown, the outlet compartment of the weir chamber D of each heater is connected by a branch pipe D to a common float box J. The float J therein is connected to and opcrates a valveK in the makeupwater supply pipe K. The latter leads to a dividing box KA from which branches K extend one into each outlet compartment B of the receptacle B. The float J operates to open the valve K and thus increases the water passing to the heaters when the water supplied through the common water supply connection A. is insuii icient to maintain a predetermined height of water level in the outlet compartments of the weir chambers D of the heaters D.

To obtain a measure of the water actually passing through each heater, a float chamber EA is provided for each heater, each chamber EA being connected as by the pipe con nection E to the still water compartment d of the corresponding heater.

E represent vapor pressure equalizing ports formed in the upper ends of the chambers EA. Working in each float chamber EA is a float FA connected to and operating suitable indicating or recording mechanism located in the corresponding mechanism casing GA. Valves L are provided in the various pipe connections whereby either heater I) may be cut out of service without interfering with the operation of the other heater, when this is desirable.

With the apparatus described the water passing into the receptacle B through the pipe A will be divided and passed in definite proportions into the two outlet compart ments B of the receptacle B and from thence into two heaters. If the weir notches C in the two weir plates are similar in number and shape and have their apices located at the same level, as will ordinarily be the case, the water supplied through the pipe A Steam for will be equally divided between the two heaters. However the weir notches may be arranged to divide the water between the different heaters, the total amount of water flowing over the weirs C will be a function of the height of water level on the supply side of the weirs, and the measuring mechanism operated by the float F will thus furnish a measure of the total amount of water supplied by the pipe A. Furthermore, the measuring apparatus operated by each float PA. Will give a correct measure of the total amount of water passing through the corresponding heater, regardless of what proportion of that water may have come from the hot well of the condenser through the pipe A, or may be makeup water supplied through the pipe K and branch pipe K or may be water of condensation formed from the steam passed scribed the best forms of my invention now known to me, it will be apparent to those skilled in the art that changes may be made in the form of the apparatus disclosed without departing from the spirit of my invention, and that undersome conditions certain features of my invention may be used without a corresponding use of other features.
